Figure C03103116D00156
Second control signal, voice signal connecting circuit 230 is controlled first switch 231 of microphones 240, perhaps connects second switch of loud speaker/microphone 250.
Externally in the connection mode, microprocessor 340 provides the 3rd control signal to voice signal connecting circuit 230.By second channel, the voice signal connecting circuit is connected to microphone and speaker-phone interface circuit 160 and coding decoder 360.If microprocessor is confirmed bell signal detection device 210 and has detected bell signal that then second relay 203 (Fig. 2) is connected in its control, communicates by letter so that the calling party of outside bell signal sets up with outside callee.
The flow chart that is to use phone of the present invention under various modes, to communicate that Fig. 7 shows.If the pstn telephone unit receives bell signal (S10) from the outside, then microprocessor checks whether telephone system is set at outside connection mode (S11).If two IP phone are not set at outside connection mode, and two IP phone do not use, and then the two IP phone of microprocessor control are set the pattern into PSTN, then, activates in the PSTN pattern by report to the police (for example, electric bell).That is, microprocessor control phone is operated under the PSTN pattern.
If phone settings are outside connection mode, and system is not in use, and then microprocessor is connected second relay 203 of hook switch circuit 200.Then external connection request side is connected (S14) with pstn telephone unit 10 automatically.At this moment, IP phone unit 30 also is dynamically connected certainly with pstn telephone unit 10.If the pstn telephone unit receives the outside initial call of external connection request from the outside, then microprocessor confirms that by bell signal transmission circuit 10 pstn telephone has received the initial call of external connection request, and, use ring warning circuit 130 that alarm is continued preset time according to initial call.Afterwards, microprocessor control figure signal processor (DSP) 350 is to generate dialing tone (S15).
The dialing tone that is generated is converted to the analog dialup signal.Then, the analog dialup signal is offered the outside outside calling party who connects of request.When outside calling party hears dialing signal, begin to input its number that will call out and password (S16).By voice signal connecting circuit 360 and the coding decoder 360 that is connected with circuit 230 by second channel, dialing signal is input to microprocessor.DSP 350 analyzes the data of being imported, and the result that will analyze offers microprocessor.
Microprocessor determine password whether with predefined password be complementary (S17).If password does not match, then microprocessor is refused external connection request (S18).If password coupling, the then outside callee IP address (S19) of microprocessor identification external connection request.Microprocessor offers LAN circuit connecting circuit 330 with the IP address, and it uses outside calling party's IP address, by the Internet externally connect between calling party and the outside callee (S20).LAN circuit connecting circuit 330 is linked into the Internet by up LAN circuit 310.
As mentioned above, if desired, the user can select two kinds of operator schemes simultaneously.For example, can activate the Internet model and outside preference pattern.When this thing happens, by first channel Internet Protocol telephone unit is connected to microphone or speaker-phone, by second channel the Internet Protocol telephone unit is connected to the telephone unit simultaneously.
Based on above-mentioned connection,, outside calling party's voice signal is input to coding decoder 360 by voice signal connecting circuit 150 and voice signal connecting circuit 230.At this moment, by second channel voice signal is input to coding decoder 360.Coding decoder is converted into the PCM data with voice signal, and the PCM data are offered DSP 350.DSP becomes the PCM data transaction data of reference format once more, and it can exchange (S21) with PCM data and outside callee or computer.In addition, DSP not only carries out the conversion of standard data, and PCM data or standard data are compressed.
By using up LAN circuit 310 and LAN circuit connecting circuit 330, microprocessor offers standard data outside callee's IP address.Microprocessor control buffer (not shown) is stored the data that will be transferred to outside callee IP address, so that outside callee's data transmission rate is mated with the data transmission rate of two phones.On the other hand, if be outside connection mode, then use the IP phone unit, and two phones are operated according to as described below with two phone settings.
Microprocessor confirms by bell signal transmission circuit 110 whether outside calling party is attempting setting up calling (S13) by two phones (pstn telephone unit 10 and IP phone unit 30) with outside callee.Its engage relay 2, from outside calling party, i.e. external connection request side's received signal automatically.Received signal be operating as S15-S22.At this moment, the user of two phones can engage in the dialogue with two external IP users by the Internet.
Talk if be through with between outside calling party and the outside callee, then the two phones of microprocessor control are made as previous pattern with it.Thereby the user can carry out the dialogue of at least one Waiting for Call.
In another one embodiment of the present invention, give pstn telephone with the call-delivery that receives in the IP phone by first channel.Thereby this embodiment externally sets up voice pathway in the connection mode, its with above-mentioned side call transmission in the opposite direction.Therefore, in this embodiment, hook switch in the microprocessor control chart 1 and voice connecting circuit, thus before being transferred to pstn telephone, use coding decoder that the grouped data that Internet Protocol telephone receives is converted into voice signal by channel 1.
The present invention also is a kind of computer program, and it comprises the code that makes processor realize the step of method of the present invention.Can be in computer-readable medium with this procedure stores, itself or be connected to phone of the present invention removably, perhaps store the memory that is arranged in or is connected to processor into.
Two according to the preferred embodiment of the invention phones connect PSTN and the Internet.Because other are operated as outside connection mode, therefore, also outside calling party and outside callee can be coupled together according to outside calling party's request.
The above embodiments and advantage only are exemplary, do not constitute limitation of the invention.The present invention goes for the equipment of other types.Description of the invention only is illustrative, does not limit the scope of the claims.For those skilled in the art, obviously various replacements, improvement and variation can be arranged.In claims, the statement that device adds function is intended to contain the structure that realizes described function, and it is not only, and structure is equal to, and also comprises equal structure.
